12 Conditions of historical comparison among ages and regions 281
tory is the study of those phenomena too wide to fit conveniently into
any particular region, it is necessary for economy's sake to know what
regions hang well enough together to be dealt with on the regional
level. Within the Oikoumenic Zone, moreover, distinguishing regions,
like the Far East and the Latin West, which form relatively constant
parts of the Oikoumenic Configuration, are of particular use in orient-
ing ourselves in the infinitely complex network of relations across the
Zone. Perhaps the most significant of such regions are the Confucian
Far East, the peninsula and island of the far South East, India and
nearby areas, and vast reaches of Central Asia, the Middle East from
the Nile and the Aegean through Iran, the Russian area, and the Occi-
dent. Certainly in addition to these are likely to be helpful at various
times overlapping regions, the Sudan, the Mediterranean Basin, the
Levant, for instance; and for relatively many purposes certain subdivi-
sions can be noted - within Western Europe, the south around the
Mediterranean, and the north on the Atlantic; within India, the Deccan
and the north; within China, again, the south and the north, the
Hoang-Ho Valley.
It is still necessary to an understanding of the role of Oikoumenic con-
ditions in interregional history, to examine the role of the Oikoumenic
regions in regard to each other. One can hardly, of course, think of the
various regions as fixed entities; nevertheless it
is
helpful to abstract fairly
constant regions within the Oikoumenic Zone, within which regions
there is a degree of cultural integration - a common religion, during
much of the time, a common literary heritage, and a common political
framework.
To
a large extent the Zone divides itself up very conveniently
into such regions, and there is a regular configuration which they form
over many centuries, which while constantly growing and changing re-
mains recognizable from the time of its formation in the first millennium
B.C.
till the Western Metamorphosis upsets
it.
For instance, the Confucian
Far East forms from Chou times a distinct region in such a sense - as it
expands, new countries like Japan are not always incorporated directly
under the imperial rule, but, recognizing common political standards,
and often enough having a common reverence for Chinese imperial au-
thority, Japan and China, as well as the lesser nations in their vicinity,
form a common diplomatic region as well as a literary and religious one.
Moreover, in the Oikoumenic Configuration this Far Eastern region has
for millennia the same general relations with other regions: overland
immediately with Central Asia, and beyond the Middle East; by several
routes, but also by religious
ties,
with India; by sea with the far South East,
and thence with other seafaring regions.
